The production of spells can be accelerated using Gems. For 10 Gems, both Spell Factory and Dark Spell Factory can get a 4x boost.

The Spell Factories can also be accelerated with the Training Potion, who will also boost the Barracks, Dark Barracks and Heroes regeneration time.

Upgrading the Spell Factory

Each upgrade level unlocks one new spell, except the Spell Factory level 4 that unlocks 2, the Jump Spell and Freeze Spell.

While being upgraded you can't start the production of new spells, but the ones already added to the queue can be used and donated.

The number of spells you can add to the queue depends on the Spell Factory level. The spells that can't do your Army will be produced and stored on the factory. Once you spend the ones on your army, the queued spells will automatically leave the Factory on the order they where produced.
